The Raktodaha Beel, located in the northern part of Bangladesh, is a significant geographical feature that has played a crucial role in the region's history and culture. This vast body of water, part of the Raktadah river, is renowned for its unique shape that resembles a beel, making it one of the largest beels in the area. The beel spans across Adamdighi Upazila in Bogra District and Raninagar Upazila in Naogaon District, with thirteen canals and other waterways flowing through it.

Historically, the Raktodaha Beel has been a site of significant battles and expeditions. Fakir Majnu Shah, a notable figure in the region, led expeditions to various parts of Bengal and Bihar under the East India Company's rule, with the beel serving as a strategic location for these campaigns. The beel was the site of a significant battle in August 1786, where Majnu Shah's forces clashed with the British army, leading to heavy casualties on both sides. This battle is remembered as the Bloody Bill due to the extensive bloodshed, with the beel's name reflecting the historical event.

The Raktodaha Beel is also known for its rich biodiversity, particularly in fish species. It was once a thriving fishing ground, providing fish for the surrounding districts of Bogra, Natore, Jaipurhat, and Naogaon. The beel's ecosystem supports a variety of fish, including Boal, Chital, Ai, Gajar, and Pabda, making it a significant source of fish for the local population. From 2003 to 2007, the NGO BRAC undertook efforts to reform the beel and promote fish farming, contributing to its conservation and sustainability.

The Raktodaha Beel is not only a natural wonder but also a testament to the region's historical and cultural heritage. Its strategic location and rich biodiversity make it a significant landmark in the Naogaon District, highlighting the district's rich history and the importance of water resources in the region's economy and culture.
